Discussion
An Arctic cold front blasted through the region last night and temperatures will be way below-normal in the Mid-Atlantic region for the next couple days. In fact, temperatures tomorrow morning will likely bottom out in the lower 20’s in many locations and low temperature records may be broken in some spots. This first Arctic blast of the season is liable to be followed by others later this month as “high-latitude blocking” sets up featuring abnormally high pressure over Greenland while at the same time an upper-level trough forms over the eastern US. This type of pattern could very well result in another blast of Arctic air for the Mid-Atlantic region by next weekend and then Thanksgiving week promises to be quite interesting with prospects for continued cold and perhaps even snow somewhere in the Northeast US.
